Highly recommended !

Pierre Guy Bareges, Digital Service Group CTO
The LITSLINK team did an excellent job in developing an app from scratch. We were in need for designer/front end/ back end and it was all managed by a PM at LITSLINK. A very tight schedule was never a problem, and we are really overwhelmed by the quality and client focus of the staff at LITSLINK.

Erik Bolmsj
We felt like we were working with a business partner rather than a service provider. Patient but persistent, fluent English-speaking, LITSLINK delivered all releases in time, within requirements and budget, performing thorough and continuous project management.

We would highly recommend them to anyone looking for a reliable software development company with a  complex challenging project and would like to appreciate their team’s professionalism, responsiveness and communication skills.

Alex Volkov, President, Mailfeed Corp. (US)
